I dont no the PUK code so i cant unblock my phone
here is what you need to know about PUK code;
When a PIN code is entered wrongly three times, the phone line will be blocked. Irrespective of the owner, it is assumed that you are not the owner of the phone line when you enter your pin wrongly.
The blocked line at this point can still be unblocked and this is where the PUK code comes in. Once you enter the PUK code, your PIN code will be reset. You can then create a ne PIN code.
To get your PUK code, if your phone is using a SIM Card, Check the SIM card Pack and you will see your PUK code there. But if you don't have a SIM card pack, you can get the PUK code from your service provider.
Call the customer care line of your service provider using another phone, request for your PUK code and it will be given to you. Note that your service provider will ask you some few questions about your line in order to be sure you are the real owner.
Note that your service provider alone is the only one that can give you your PUK code because it's only your service provider that has it.
